A little less than 30 minutes before purposefully driving her minivan off a pier with her four children inside, Lashanda Armstrong updated her Facebook status from her Blackberry: "I'm sorry everyone forgive me please for what I'm gonna do… This is it!!!"

Armstrong and three of her children—Landon Pierre, 5; Lance Pierre, 2; and 11-month-old Lainaina Pierre—drowned in the Hudson River in Newburgh, NY. Armstrong's 10-year-old son, Lashaun, managed to escape out a window as the van sank. Armstrong had been acting strangely in recent, telling a friend she felt like someone was watching her. She and her boyfriend had had a "vicious fight" before Armstrong drove into the water, according to the Times.
